Abstract
AIM: To investigate the clinical effect of endoscopic stenting combined with neoadjuvant chemotherapy in the treatment of malignant colorectal obstruction.
METHODS: A retrospective analysis of 75 malignant colorectal obstruction patients who were treated at Liaoning Provincial People's Hospital between 2003 and 2008 was performed. The patients were divided into three groups, a control group (n = 30) treated using traditional methods, a stent placement group (n = 30) treated using self-expanding metal stents, and a stent placement plus chemotherapy group (n = 15) treated using self-expanding metal stents in combination with neoadjuvant chemotherapy.
RESULTS: The percentage of surgical patients undergoing colostomy was significantly higher in the control group than in the stent placement group and the stent placement plus chemotherapy group (62.5% vs 30.0%, 25.0%, χ2 = 4.619, 4.500, both P < 0.05). The tumor resection rate was significantly lower in the control group than in the stent placement group and the stent placement plus chemotherapy group (37.5% vs 70.0%, 75.0%, χ2 = 4.619, 4.500, both P < 0.05). The radical surgery rate was significantly higher in the stent placement plus chemotherapy than in the control group (41.7% vs 12.5%, χ2 = 3.938, P < 0.05), but showed no significant difference between the control group and stent placement group (χ2 = 0.059, P > 0.05). The five-year survival rate was significantly higher in the stent placement plus chemotherapy group than in the control group (26.7% vs 3.3%, χ2 = 5.513, P < 0.05), but showed no significant difference between the control group and stent placement group (χ2 = 1.071, P > 0.05).
CONCLUSION: Endoscopic stenting combined with neoadjuvant chemotherapy can effectively improve tumor resection rate and radical surgery rate and prolong survival time in patients with advanced colorectal cancer.
